The utility model relates to a slewing bearing flange of a gantry crane with a large-diameter slewing bearing, which is manufactured by ingeniously combining and applying traditional metal processing technologies. The utility model has the technical scheme that the slewing bearing flange of the gantry crane comprises a flange plate and a barrel body, wherein the flange plate and the transition cylindrical barrel body are uniformly provided with knee plates at intervals; the flange plate and the barrel body are welded together. A manufacturing process of the flange comprises the following steps of: forging a bar material into a straight square blank with allowance, thermally treating and roughly processing the bar material through a machine; then, pressing into required equal circular ring blocks by an oil pressing machine, cutting the allowance, chamfering, assembling a sample on a platform, and splicing and welding into a circular ring; and finally, finely processing into a flange plate with required size. The utility model has the advantages easy manufacturing, high finished product rate and low cost.read more
